Port Gardner Storage Facility Volume 7 Attachment O Page 14 CITY OF EVERETT ⋅ 3200 Cedar Street ⋅ Everett, WA 98201 ⋅ (425) 257-8800 ⋅ Fax (425) 257-8882 Q65 - Drawing CX-10-2003, Keynotes 23 and 25 call for demolition of 36” CCP. Does this pipe have any wrapped reinforcement that requires special cutting provisions? Does this remaining pipe have to be capped have to be capped? Provide detail. The 36” CCP per Keynotes 23 and 25 on Drawing CX-10-2003 is to be demolished but the remaining pipe does not need to be capped. The Engineer is not aware of any reinforcing wrapping that requires special cutting provisions. Q66 - Drawing CX-10-2003, Keynotes 26 and 7 call for demolition of 30” CCP and buried structural supports. Provide and special cutting details for 30” pipe. With regard to the structural supports, provide details (not just location) on these too and the depth to which they are to be cut, if piles. If you are going to defer to Drawing B-9007 and B- 9008, provide the pile numbers or cloud the ones to be modified. Is this pipe to be capped where left in place? Provide details. The hatched pipe is to be removed. The remaining length is to be repurposed and connected to new piping per the drawings. On the west end of the 30” CCP in question, at Keynote #7, pile #25 and its pipe support, shown on record drawing B-9007, must be removed to allow installation of the valve vault as shown on Drawing D-30-3004. Pile #24 and its pipe support will remain to support the repurposed 30” CCO remaining. Piles #26 and #27 and their pipe supports should not interfere with the new work and should not have to be removed. On the east side of the 30” CCP in question, at Keynote #26, piles #3-9 and their pipe supports, shown on record drawing B-9007, must be demolished to an elevation 6” minimum below the new pipe invert elevation. The existing pipe supports and pile caps are shown on record drawing B-9706, piles are shown on record drawing B-9008. The approximate invert elevation of the existing 30” CCP to be demolished, based on elevations given on record drawing B-9017, varies from 9.4 to 8.5 in the project datum. The approximate invert elevation of the NEW 30” pipe to replace the demolished pipe varies between 7.2 and 6.7. From this information, the depth of demolition of pile and pipe supports #3-9 can be determined. Q67 - Drawing CX-10-2003, Keynote14 call for abandoning pipe in place. Are there any requirements to this activity? No abandonment requirements beyond disconnecting them and leaving them in place. Q68 - Drawing CX-10-2003, Keynote16 call for cutting and demolishing of wooden pile. Please provide details of the pile. Details of the wooden piles are not available but were observed to range between 12 and 18 inches in diameter. There are no pile caps. The contractor should demolish the wooden piles that interfere with new facilities to the depth necessary to avoid interference with new facilities.
